^aThe prior low and high values are, respectively, the minimum of the expert prior lows and the maximum of the expert prior highs.

^bThe prior median is the average of the expert prior medians.

^cThe Assessment column describes how well the estimate aligned with expert knowledge, based on low and high values provided by experts that were not used in the size estimation model.
